I bought a home a couple years ago that was built in 1954. The majority of the walls/ ceilings are still plaster. Unfortunately it still has popcorn ceilings. I made an attempt last summer to remove them and smooth them out. I scraped a little bit off before I got started and took it to get analyzed for asbestos before starting. The results were strange. They told me it was 100% gypsum plaster. I went home and tarped off a section of the living room and soaked the heck out of the ceiling with a hudson sprayer. When I went to start scraping it was all still hard as a rock. Apparently my ceilings were textured using plaster. I've never heard of this and know one I know has either. I decided to try one of the bedrooms because the texture was much softer and came off when I ran my fingers across it. No luck. In the bedroom they had actually used a soft material to texture ON TOP OF the plaster texture!
I'm wondering if anyone has advice as to either how to remove this stuff (keep in mind I took a WOOD FLOOR SCRAPER to this stuff and it barely made a dent) or, cover it up. I've already started covering the section I started on in the living room with 3/8" drywall, but should I just remove the ceiling altogether and start from scratch? Any help is appreciated. Thanks.
